A connecting device suitable for exposed loads outside the cabin of a space vehicle

Abstract

The invention provides a connecting device suitable for an outboard exposed loader of a spacecraft. The device comprises a loader installing port and a loader locking and pointing assembly; the loader installing port is composed of a ball body structure and a loader installing structure and is integrally designed; the loader installing structure is used for fixing the exposed loader; and the loader locking and pointing assembly utilizes a pretightening fixing method to fix the ball body structure. The loader locking and pointing assembly comprises a handle A, a guiding and riving pin A, an anti-loose device, a clamping ring, a shell A, a spring a, a ball body safe blocking plate, a ball body safe blocking plate limiting block, a driven friction cup, a limiting block driving spring, a lead screw A, a lead screw A blocking ring, a driving friction cup, a disk spring and an end cover. The anti-loose device comprises an anti-loose device shell, an anti-loose spring, an anti-loose ball and a lead screw B blocking ring. The connecting device can achieve guided installation, reliable fixing, accurate pointing and overload protection of the exposed loader and accordingly provides technical support for quickly installing the exposed loader at the outboard set position.

Description

technical field [0001] The invention belongs to the field of space application equipment, and in particular relates to a connecting device suitable for exposed loads outside the cabin of a space vehicle. Background technique [0002] Space stations, manned spacecraft and other space vehicles are equipped with a large number of astronaut handles on the outer wall of the cabin to facilitate the movement and fixation of astronauts when they leave the cabin. For example, using some of the handles to fix small exposed loads outside the cabin will greatly expand the space vehicle. exposure test capabilities. At present, the International Space Station has used the extravehicular handle to fix the material exposure test box for long-term material exposure experiments. [0003] However, for the exposed load outside the cabin, the connection device in the prior art cannot automatically capture the exposed load outside the cabin, and has poor self-locking function and low reliability...
